Q: Ck engine soon light is on

If your vehicle’s check engine light illuminates, there is a malfunction that should be investigated and repaired. However, the seriousness of the malfunction is hard to judge unless and until a Code Scanner is used by the Mechanic to download the specific trouble codes from your car’s computer (PCM or ECU) that have caused the light to turn on. Sometimes the check engine light will illuminate if the gas cap is loose. If the rubber seal on the gas cap is intact and the cap is tight, all other causes of the light illuminating would have to be evaluated in a check engine light diagnostic. During such a diagnostic, a certified mechanic from YourMechanic would use a code scanner to retrieve diagnostic trouble code(s) from your car’s PCM. Using those codes the appropriate individual vehicle components or sub-systems (often a sensor, circuit, and the like) are tested to pinpoint the cause of the fault or the reason why the check engine light has illuminated. Once the faulty part or component is identified, it is explained to your satisfaction and the mechanic will let you know of the cost to repair. If you schedule the recommended diagnostic, the mechanic will resolve this promptly for you.
